Living rent free (again not assuming that is your situation, but guessing many parents with adult children at home don't charge them rent), it can be easy to spend that money and then when you are on your own, having problems budgeting.

My parents struggled really hard (and still do) financially so my sister and I are trying to really break out of that mold as adults. 

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

I have tried asking guests to invite every adult staying into the Airbnb booking. 

Seminole for Example has a lot of great traffic and tons of spots to eat, drink, socialize for adults and kids.I know Cape Coral is picking up in terms of STR's with the complettion of the 7 Mile Island and more construction lately. 

adults=1&am...Thanks in advance,Aaron

Look I was a "troubled youth" and I unfortunately tacked on 5 ADULT f5 felonies and nearly 5 years of lock up time by the age of 17!

We have had people try to move into a one bedroom with two adults and a baby.  

Not a solution, but going forward...Have all adult tenant prospects fill out applications which require their social security number, driver's license number, their birth date, their current address and their prior address.

This is because, as adults, we ALL have *some* familiarity with cars and money and we know how the business world works!
